#31 is right about bonuses being expected or even guaranteed in some jobs, but it's not just limited to government. I know someone in finance; in his job, annual bonus is performance-based but an expected part of compensation, and can be ~1-3x salary.

Oh OP you should be happy and proud that your wife is so hard working and has the potential to do great things. You're married.. So in one way her money is also yours. I'm sure she'll share it with you.
